their share of failures and set backs I can understand your mom's comment as we don't want to see our children try again and again and meet with pain and disappointment over and over....but I don't agree with her comments to you.
It's when we reach for things that are difficult that we learn the most in life...when the road is darkest and the pain is greatest we grow as souls and as people.
I want my children to reach for the stars and my oldest DD who knows that her 3 younger siblings came via DE's after a long ttc struggle has told me that my journey has inspired her to dream BIG.
I think you have to forgive your mom for loving you so much and wanting to shelter you...but you should clue her in to your dream and ask her if she has any regrets in her life that she didn't strive for her greatest desires.
